Description

The invention relates to an actuating device for the common admission of at least two different elements of a motor vehicle door lock, with at least one cable with soul and shell, the cable is equipped with at least two power transmission units in their longitudinal extent, which for interaction with on the one hand a first element and on the other a second element are arranged upon actuation of the cable, and wherein the one of the two elements is designed as an actuating lever.

Actuators for motor vehicle door locks usually have a handle, such as an inside door handle and / or outside door handle, with the help of individual elements in the interior of the motor vehicle door lock, in the example, an internal operating lever and / or an external operating lever acted upon. In general, a release lever is in mechanical engagement with the inside operating lever and / or outside operating lever. With the help of the release lever, a pawl is regularly lifted from its engagement with a catch, so that the catch can open spring-assisted and releases a previously captured locking pin. As a result, the motor vehicle door equipped with the motor vehicle door lock concerned can be opened.

In the generic state of the art according to the DE 10 2007 012 684 A1 In an actuator of the construction described above, the procedure is such that a lock assembly is actuated by generating a tensile force on the core of the cable. In this context, according to the local embodiment according to 5 also two different levers at the same time experience an impulse with the help of the soul. For this purpose, spaced-apart cable nipples are connected to the soul. The essence here is to lock in particular a sliding door in a motor vehicle in a specific (open) position.

The further prior art according to the DE 43 27 782 A1 deals with a door lock device with a one-way door opening mechanism. For this purpose, the soul of a cable is engaged with a flange and also has a pressure member. By doing so, an inside lock button is finally transferred to an unlatched position. That is, when an inner opening handle is applied, the associated door opening operation is performed and performed even when the vehicle door lock is still in the locked state. Because then the soul of the cable works so that the unlocked state is taken and at the same time accomplished a door opening.

The known measures have proven themselves in principle, however, are structurally designed partly expensive. Incidentally, in motor vehicle door locks, there are nowadays additional requirements which have hitherto not been adequately taken into account. Currently, motor vehicle door locks are often equipped with additional closing / opening devices that are currently (still) used in high-priced cars, but may be able to open up the mass market in the future.

A Zuzieheinrichtung is usually used to ensure that by means of a conventional electric motor for a motor Zuuzhung on a flap or door. As a result, the locking mechanism of the motor vehicle door lock, so usually the combination of pawl and rotary latch, after reaching a certain functional position, usually the Vorraststellung, transferred to its end position respectively main rest position. This results in a particularly convenient approach because an operator only has to spend the associated door or flap in the pre-locking position and then ensures the closing device for the complete closing process. An example of such a closing device describes the utility model DE 20 2008 007 310 U1 the applicant, in which the drive for the closing device is designed as a linear drive and operates on a lever which is pivotally connected to a Ziehiehklinke. The closing pawl engages in a contour on the catch and causes the desired closing movement.

In principle, opening aids are also known which ensure that an associated locking mechanism of the motor vehicle door lock can be opened by motor. An example of such an opening device or opening aid is in the DE 10 2004 052 599 A1 described. Here, too, the primary aim is to achieve a better comfort.

In the known Zuzieheinrichtungen or opening devices problems may arise when, for example, when pulling a jacket, a coat or a similar piece of clothing or even a body part of the operator enters the gap between the closing door and a motor vehicle body. This circumstance usually leads to the closing device being switched off. In such a case, however, an operator intuitively proceeds by acting on the outside door handle and expects that the closing device will be immediately ineffective and at the same time the vehicle door will be an opening learns to release the jammed part. So far, there are no convincing solutions that map and reflect this user interface in a structurally simple way.

The invention is based on the technical problem of further developing such an actuating device in such a way that operating and safety-problematic states in the case of closing / opening devices are avoided with little effort.

To solve this technical problem, a generic actuator for jointly acting on at least two different elements of a motor vehicle door lock in the invention is characterized in that it is at the other of the two elements anyway on the locking working Zuzieh- / opening element. In other words, the two different elements of the motor vehicle door lock on the one hand as an operating lever and on the other hand designed as a closing / opening element or hereby interacting element which operates on the locking mechanism.

Usually, the first element is designed as an actuating lever, while it is the second element is a Zuziehelement. Both elements interact with the cable, which has for this purpose on the two power transmission units. Thus, as soon as the cable is subjected to a force, both the actuating lever and the closing element undergo an admission via their respectively assigned power transmission units.

The operating lever is an inside operating lever, an outside operating lever, an operating main lever, etc. The inside operating lever is regularly urged by an inside door handle. In contrast, the external actuating lever is mechanically connected to an outer door handle in operative connection. The operating main lever may be interposed between the inside operating lever and the outside operating lever, or may also be acted upon by a motor drive.

As soon as, in the example, the inner door handle is actuated by an operator, the cable pulling the inner door handle with the inner operating lever also experiences an action. The cable is force-deflected. As a result, both the internal operating lever and the closing element or the closing / opening element experience an application.

Thus, if the closing element is in the example case in engagement with the locking mechanism and the inner door handle is acted upon by the operator with force, this force introduction ensures that both the internal operating lever experiences an actuation and the closing element. As a consequence, as a rule, the locking mechanism is opened and at the same time a closing device with the tightening element is transferred to an ineffective state.

For this purpose, the acted upon by the inner door handle operating lever operates on the release lever, which in turn lifts the pawl of the catch. This is done by a mechanical coupling of the first power transmission unit of the cable with the inside operating lever. Since the cable interacts with the closing element via the further second power transmission unit with temporal overlap, the closing element is removed from its engagement with the locking mechanism. For this purpose, the Zuziehelement is usually pivoted away from a rotary latch, with which it was previously engaged. - Mostly, however, the measures described are observed on the external operating lever chain, that is, in the interplay of the outer door handle with the associated external operating lever. In this case, the external actuating lever acts on the release lever and at the same time the Zuziehelement is pivoted away from the rotary latch by the deflected cable.

This is particularly advantageous for the case that the closing element is designed as a closing pawl acting on the catch of the locking mechanism. In most cases, the closing pawl is assigned a lever and in particular a closing lever, which is acted on by a closing drive. Once the catch has reached a certain predetermined position, usually the pre-locking position, the closing pawl falls into an associated Zuziehkontur on the rotary latch. At the same time, the closing drive is started and acts on the lever or closing lever in such a way that the closing pawl connected to the lever transfers the rotary latch from the pre-locking position into the end position or main-locking position. If it happens during this process that, for example, a garment is trapped in the gap between the motor vehicle body and the vehicle door to be pulled, a manual action on the outside door handle on the part of the operator immediately ensures that the closing pawl is (as it were) ejected from the second element and at the same time the motor vehicle door lock undergoes an opening.

Both processes do not necessarily have to take place simultaneously and synchronously, but it is sufficient that a temporal overlap is observed and in particular the closing pawl has left the rotary latch as soon as it ( spring assisted) pivoted into its open position after lifting the pawl.

In order to realize the two power transmission units, the cable is generally suspended in the first element, whereby the first power transmission unit is defined. The first element is generally the external operating lever to which the first power transmission unit is associated. The second element spaced therefrom is usually designed as a closing pawl. At this point, the cable is equipped with a driving drum as a second power transmission unit.

In general, the driving drum interacts with actuation of the cable with a stop on an ejector, which in turn works on the closing pawl. The stop is regularly designed as a sheet stop with slot recording. Through the slot receiving the cable is mostly passed. This happens beyond the entrainment drum, which - as described - interacts with the stop on the ejector lever.

So as soon as the driving drum rests against the stop and pivoted in this way the ejector lever, the ejector lever is able to bring the Zuziehelement or Zuziehklinke out of engagement with the locking mechanism. For this purpose, the ejector moves when it is acted upon against an actuating pin of the closing element. As a result, the Zuziehelement is removed from his (eventual) intervention on the locking mechanism.

The ejector lever can also be functionally and in addition to its operative connection with the soul of the cable mechanically connected to an internal operating lever. In this case, the interpretation is usually made such that the internal operating lever works via an internal operating ejector lever when actuated on the ejector lever for the closing element. That is, an application of the inner operation lever by means of the inner door handle causes the inner operation ejector lever to be applied as well. The internal operation ejector lever now operates on the ejector lever for the closing element in a similar manner as when the cable pull is applied. That is, this operation also corresponds to mechanically disengaging the cinching member from the ratchet via the inner operation ejector lever of the cinching member ejector lever.

From a topological point of view, it has been found that the second element or the ejector lever and the (outer) actuating lever are arranged in a parallel plane in comparison to a scarf plane. On the other hand, the inside operating lever and also the inside operating ejector lever are located in a plane perpendicular to the scarf plane. Thereby, it is necessary to provide the inside operation ejector lever for converting the movement of the inside operation lever in the plane perpendicular to the scarf plane into a rotational movement in or parallel to that scarf plane, with the aid of which the ejector lever associated with the closing element will receive the desired impingement.

As a result, an actuating device for a motor vehicle door lock is provided, which is typically suitable and designed for jointly acting on the one hand the external operating lever and on the other hand, the closing pawl of a closing device. As soon as the cable pull of the actuating device is thus subjected to a corresponding force (pulling), both the external actuating lever are deflected and the closing pawl is lifted off the locking mechanism. This generally happens with overlapping in time, at least in such a way that the closing pawl is mechanically lifted off the ratchet as soon as the ratchet starts its opening movement (spring-assisted).

As a result, a significant increase in comfort is observed in a simple manner. Because any malfunction or security problems, for example during the closing process can be terminated by an operator immediately, quickly and in an intuitive manner simply by the fact that the operator operates the outside door handle. As a result, the closing process is interrupted immediately, because the closing element is lifted from the locking mechanism by means of the ejector lever. At the same time, the motor vehicle door subjected to such a load experiences the desired opening. All this is possible quickly and with little constructive and assembly-technical effort, because the cable is equipped as a connection between the outer door handle and the outer lever and the Zuziehklinke respectively the Zuziehklinke as assigned ejector lever with only two suspension points. These suspension points or power transmission units can be easily realized. Because the second power transmission unit or realized at this point Mitnahme drum can already be attached to the factory cable, so that the cable must be mounted only in the outer operating lever for the realization of the first power transmission unit during assembly. Here are the main benefits.

In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment; show it:

1 the actuator according to the invention in a schematic overview and

2 a motor vehicle door lock with the actuating device according to the invention in concrete design.

In the 1 and 2 is an actuating device for jointly acting on at least two elements 1 . 2 a motor vehicle door lock 3 shown. The actuator has for this purpose a cable 4 . 5 as an essential element. The cable 4 . 5 is with a soul 4 and a shell 5 equipped.

At the cable 4 . 5 Is it in the embodiment to a Bowden cable 4 . 5 , Its shell 5 is stationary and is based on the motor vehicle door lock 3 from. In contrast, the inside of the shell 5 movable soul 4 in particular a pulling movement of a handle 6 to the two already mentioned elements 1 . 2 of the motor vehicle door lock 3 exercise, as this is an arrow in the 1 represents. In the context of the embodiment, it is the handle 6 around an outside door handle 6 , which is not restrictive and mandatory.

The soul 4 of the cable 4 . 5 is with at least two power transmission units 7 . 8th equipped in their longitudinal extension, which are spaced from each other. Actually one recognizes by means of the 1 a first power transmission unit 7 end of the soul 4 and a second power transmission unit spaced therefrom 8th along the length of the soul 4 , In the first power transmission unit 7 it is a hook or a similar connecting element, with the help of the soul 4 end in an opening of the first element 1 is hung. In contrast, the second power transmission unit 8th as a driving drum 8th designed, the factory or later on the soul 4 is attached.

The in the longitudinal extension of the soul 4 spaced from each other arranged power transmission units 7 . 8th are to interact with on the one hand the first element 1 and on the other hand the second element 2 at a charge to the soul 4 with the help of the handle 6 set up. In fact, an imposition of the soul 4 for being the first element 1 or at this point realized external operating lever 1 of the motor vehicle door lock 3 around his axis 9 is pivoted clockwise as an arrow in 1 suggests. Also the second element 2 experiences when the soul is charged 4 a pivoting movement clockwise about its associated axis 10 , At the second element 2 In the example, this is an ejector lever 2 which is a closing element 11 assigned. The closing element 11 is mechanical with a closing lever 12 connected. Actually, it is the closing element 11 one turnable on the closing lever 12 mounted closing pawl 11 , The closing lever 12 is about a purely in 2 indicated cable 13 from a sewing drive 14 applied. The Zuziehan drive 14 , the cable pull 13 , the closing lever 12 and finally the closing element or the closing pawl 11 together make up a closing device 11 . 12 . 13 . 14 ,

As already explained, the first element is 1 in the embodiment as an external operating lever 1 designed. Basically, it could be at the first element 1 also to an internal operating lever or generally an operating lever of the motor vehicle door lock 3 act. The closing element 11 works on a locking mechanism 15 . 16 which is a catch 15 and one with the catch 15 in the usual way interacting pawl 16 composed. The closing element or the closing pawl 11 engages in a contour or Zuziehkontur 17 at the rotary latch 15 a to the locking mechanism 15 . 16 contracting. In this way, even a previously from the locking mechanism 15 . 16 trapped and tightened with a motor vehicle door bolt tightened. The associated motor vehicle door moves closing to the vehicle body.

This process is done with the help of the closing device 11 . 12 . 13 . 14 accomplished. The closing device 11 . 12 . 13 . 14 or the Zuziehantrieb 14 is then started in the embodiment when the catch 15 is in its pre-locked position. Then the Zuziehelement or Zuziehklinke 11 into the contour 17 at the rotary latch 15 come to mind. At the same time the Zuziehantrieb 14 started and applied to the cable 13 in the in 2 Plotted arrow direction. As a consequence, the closing lever experiences 12 which also in the 2 indicated counterclockwise movement about its axis and ensures that in the contour 17 at the rotary latch 15 sunken closing pawl 11 the catch 15 pivoted in the indicated clockwise direction and transferred from the pre-locking position to the main locking position.

If, in the described closing process, a piece of clothing, for example, is clamped between the motor vehicle door and the motor vehicle body, an operator can do so by applying the handle or the outside door handle 6 mechanically interrupt the closing process and at the same time open the vehicle door. Actually, namely, the admission of the outer door handle 6 for the in 1 and also in 2 indicated pulling force of the soul 4 of the cable 4 . 5 , As a result, the outside operating lever rotates 1 in a clockwise direction cf. 1 ) and acts in this case a trigger lever, not explicitly shown, which in turn the pawl 16 from the rotary latch 15 takes off. For this purpose corresponds to a movement of the pawl 16 counterclockwise about its axis, like the 2 indicated by an arrow.

Before or at the same time the driving drum moves 8th against a stop 18 on the second element 2 or the Zuziehklinke 11 associated ejector lever 2 , The stop 18 is designed as a sheet stop and also has a slot recording 19 , Through the slot recording 19 is the soul 4 of the cable 4 . 5 passed. In fact, the soul goes through 4 the relevant slot recording 19 beyond the takeaway drum 18 ,

Once the soul 4 with the help of the outside door handle 6 in the illustrated arrow direction is applied pulling, which ensures against the stop 18 moving takeaway drum 8th at the soul 4 for the ejector lever 2 around his axis 20 - As indicated by an arrow - is pivoted clockwise. This clockwise movement of the ejector lever 2 As a result, the closing pawl 11 from the contour 17 at the rotary latch 15 is lifted. For this purpose, the Zuziehklinke 11 via an actuating pin 21 , against which the ejector lever 2 at its admission by means of the driving drum 8th moves.

As a consequence of this is the Zuziehantrieb 11 . 12 . 13 . 14 or the closing element respectively the closing pawl 11 mechanically from the locking mechanism 15 . 16 separated. The locking mechanism 15 . 16 is therefore no longer applied in a moving sense. This may cause the catch 15 after lifting the pawl 16 spring-assisted, by making a counterclockwise movement - against the direction of the closing movement. A previously from the catch 15 captive and not explicitly shown locking bolt is released. The same applies to a motor vehicle door to which the locking bolt is connected.

The closing pawl 11 assigned ejector lever 2 is not just about the soul 4 and the cable 4 . 5 with the outside door handle 6 mechanically connected. But the ejector lever 2 In addition, it can functionally and additionally mechanically with an internal operating lever 22 interact. The inside operating lever 22 is in turn mechanically connected to an internal door handle, not shown. An application of the inner door handle causes the inner operating lever 22 - As indicated - performs a clockwise movement about its axis. This clockwise movement of the inside actuating lever 22 upon application of the inner door handle, not shown, is via an internal actuating ejector lever 23 on the closing pawl 11 associated ejector lever 2 transfer.

Actually, the clockwise rotation of the inside operating lever corresponds 22 to that the inside operation ejector lever 23 as a result, rotated counterclockwise. Thereby comes the inside operation ejector lever 23 with a stop edge 24 on the ejector lever 2 engaged. That is, the inside operating lever 22 works via the inside operation ejector lever 23 at its application to the Zuziehklinke 11 associated ejector lever 2 , To do this, the internal operating ejector lever moves 23 in its counterclockwise rotation against the stop 24 and ensures that the ejector lever 2 - as in the case of his use of the outside door handle 6 - is pivoted clockwise and the Ziehiehklinke 11 from the rotary latch 15 takes off.

It can be seen that the ejector lever 2 and the outside operating lever 1 in a parallel plane compared to one from the ratchet 15 . 16 spanned Gesperreebene are arranged. In contrast, there are the internal operating lever 22 and the inside operation ejector lever 23 in a plane perpendicular to the spicery plane. These are the locking mechanism 15 . 16 in an L-leg of an L-shaped lock case 25 stored, whereas the inside operating lever 22 and also the inside operation ejector lever 23 experience a storage in the other L-leg. The ejector lever 2 and also the outside operating lever 1 are in contrast in a not explicitly shown and with the lock case 25 stored connected lock lid.

In a further, not shown embodiment, the driving drum 8th also on the shell 5 of the cable ( 4 . 5 ) to be ordered.
